Recently I saw a patient who suffered with recurrent attacks of vertigo. Vertigo is an awful experience where suddenly the patient’s surroundings start to spin around – it is like being on a very fast merry-go-round at a carnival with the world spinning around you. It is associated with nausea, sometimes vomiting and an inability to walk without falling. This patient visited the balance and vertigo center at a major hospital where a physiotherapist performed the Epley maneuver on her, to stop the vertigo attack. For more information on Epley maneuver see She had suffered with these vertigo attacks every 3 to 4 months for several years. She found that vitamin D supplements helped her to a small degree but did not prevent the attacks. I had prescribed her a course of vitamin K capsules in a dose of 3 daily, to help her build up her low bone density to prevent osteoporosis. Coincidentally after 6 months of taking my brand of vitamin K capsules, she discovered that her vertigo disappeared. She was delighted as she hated these unpredictable and incapacitating attacks of vertigo. Liver doctor vitamin K capsules are the most complete Vitamin K formula containing 3 types of vitamin K – namely vitamin K1 and both forms of MK4 and MK7 of Vitamin K2 The virtue of this formula is that it provides the precise amount of the long acting MK-7 form of Vitamin K2 that recent human studies have shown provides optimal K2 levels over a 24-hour period. The MK-4 version is also included to provide the rapid increase in vitamin K blood levels that may account for its beneficial effects. We now know that insufficient levels of vitamin K2 can lead to decreased bone mineral density, a key factor in osteoporosis, and an excess of calcium in the arterial wall, which increases the risk of heart disease. The total dose is 2,200 mcg of vitamin K per capsule in the liver doctor brand of vitamin K. In Japan, vitamin K2 has been shown to substantially improve osteoporosis when given either as a high-dose prescription agent or in the staple Japanese dish called Natto, which is very rich in K2 Her vertigo was caused by a disorder of her inner ear, specifically in the part of the inner ear called the vestibule, which sends messages to the brain about a person’s position in space. The vestibule is the organ of equilibrium and registers the body's movements, thus ensuring that we can keep our balance. The vestibule consists of three ring-shaped passages, oriented in three different planes. All three passages are filled with fluid that moves in accordance with the body's movements. In addition to the fluid, these passages also contain thousands of hair fibers which react to the movement of the fluid sending little impulses to the brain. The brain then decodes these impulses which are used to help the body keep its balance. Crystals of calcium carbonate are found embedded in parts of the vestibule and are vital for its function of balance, stability and spatial orientation. If there is not enough calcium in the right places in the vestibule, vertigo may occur. Vitamin K supplements help to put this calcium in the right places The above statements have not been evaluated by the FDA and are not intended to diagnose, treat or cure any disease.
